I would suggest working on submitting changes to ethtool to enable the feature. Along with the ethtool patch to add the functionality you could also publish the ixgbe changes required to use to the feature. Doing both of them at the same time. You would have to go through the net-dev mail list to get this approved.

Since you aren't being specific it's hard to know. However, if it's Windows this might be harder to do if MS doesn't require it as an API change for the NDIS drivers.
